I just wondered if every enemy had a hybrid or if some have not been implemented yet.  If it's limited, is there a list somewhere?

all enemies have a hybrid. if you get a duplicate offspring, you will get an unknown creature instead.

Right on!  I just could not seem to get a hybrid for one of the enemies, and I wanted to make sure I wasn't just wasting my time chasing after something that didn't exist.  Excellent work so far, boss.

I have been trying to get a rubby beetle hybrid but I keep getting unknown creature even though I don't have it
